Hello!
Convinced my colleague to buy the 2016 B9 A4 1.4. After just 2300 kilometres, we just noticed these bumps on the front and rear right tyres. Can someone please tell me what are these? What are these caused by, and how dangerous?
These are Hankook tyres as opposed to the Pirelli that I have in my B8 A4.
Thank you!
